How to Grow and Care

Acacia requires full sunlight and grows in nearly any type of soil, including sand, clay, or soil that is highly alkaline or acidic. Although Acacia prefers well-drained soil, it tolerates muddy soil for short periods of time. Acacia is basically a plant-it-and-forget-it type of tree, although a young tree may need protection from wildlife while it develops its defense system. During the first year, the tree benefits from an orchid fertilizer every three to four weeks. After that time, you can feed the tree a general purpose fertilizer once every year, but it isn't an absolute requirement. Acacia requires little or no water.

Acacia may need occasional pruning during the dry months. Avoid pruning leafy, green areas and trim only dead growth.

Although the tree is disease-resistant, it can sometimes be affected by a fungal disease known as anthracnose. Additionally, watch for pests such as aphids, thrips, mites and scale… – See more at: How to Grow and Care for Acacia
